BALTIMORE (AP) — The Tampa Bay Rays have to wait at least one more day before taking their swings against former teammate Alex Cobb.

Cobb, now with the Baltimore Orioles, was scheduled to face his old team on Tuesday night before the game was postponed by rain.

Thus, Cobb will start Wednesday in the delayed start of this series between the only two AL East teams with losing records.

The rainout will be made up as part of single-admission doubleheader on May 12.

It was the 27th major league game to be postponed this season, the most related to weather through April since the commissioner's office started keeping records in 1986. Detroit's game at Pittsburgh was washed out later Tuesday, raising the total to 28.

Cobb, 30, spent his entire career with the Rays before signing with Baltimore as a free agent on March 21. Over six years with Tampa Bay, the right-hander was 48-35 and one of the leaders of the staff.

"He was a crucial part to this organization's success," Rays starter Chris Archer said. "He's a big-game pitcher and somebody who's very consistent, very routine oriented. The competitive nature rubbed off on me and rubbed off on the other guys in this clubhouse as well."

Cobb signed a $57 million, four-year deal with the Orioles, who will be counting on him to deliver the same kind of pitching and leadership in Baltimore.

Thus far, it hasn't gone well. Cobb got off to a late start because he missed most of spring training, and since his return he's gone 0-2 with a 15.43 ERA.

"Abbreviation has affected that," Rays manager Kevin Cash said. "He's going to get going here. Hopefully he can wait one more start before he does."

Brad Miller was down to bat cleanup for the Rays on Tuesday night before the game was called. Miller knew better than to chat with his old friend beforehand.

"Definitely wouldn't talk to him on his start days," Miller said. "Thought about maybe texting him just to rattle him a little bit, but ... ."

Miller won't know what to think when he sees Cobb wearing the orange and black of the Orioles.

"It's definitely going to be weird seeing him on the mound," Miller said. "I miss Cobb a lot. He was the ultimate competitor."

And that, Miller contends, is what sets Cobb apart from most pitchers.

"He's a bulldog. Really intense, kind of an old-school throwback starting pitcher," Miller said. "He's going to go out there and do anything he can for his team. So that, for me, is obviously his biggest trait."

The rainout came at an opportune time for the Orioles, who are hampered by injuries and have lost nine of 10 games to fall 11 games under .500 (6-17).

Baltimore's projected starting lineup did not include infielder Tim Beckham, who's been bothered by a groin injury and is expected to land on the 10-day disabled list.

With Beckham out and Trey Mancini playing with a tender right knee, manager Buck Showalter would have been operating with a short bench.

Help is on the way: Baltimore claimed utility infielder Jace Peterson on waivers from the New York Yankees. He's expected to arrive Wednesday.
